>Sometimes the simplest way to set up a threaded program
is to make all the GTK+ calls in a single thread. In such
a program, you should still call g_threads_init(), but
don't need to call gdk_threads_init(), gkd_threads_enter(),
and gdk_threads_leave().</P
><P
>If you set your program up this way, how then do you get
the thread making GTK+ calls and running the main loop
to do something in response to another thread?</P
><P
>An easy way to do it is to take advantage of the fact that
the GLib main loop functions are all thread safe, and can
be called from any thread by adding an idle function
with g_idle_add(). The function provided will be called
at the next opportunity by the main thread. If you want
your function to take priority over event handling and
drawing, you can instead use g_idle_add_full() and pass
in a priority of G_PRIORITY_HIGH.</P
